Habitat supply modeling for multiple, terrestrial wildlife species was applied to the western portion of the Quesnel Timber Supply Area (TSA) in British Columbia. The ultimate goal was to provide information on selected wildlife for use in multiple-accounts, trade-off analyses intended to support sustainable management of timber and other affected resource values. Objectives in this first year of the planned two-year project were to: (1) prepare a list of terrestrial vertebrate species that would represent a cross-section of habitat requirements and indicators, (2) research an account of habitat needs for each species, (3) develop habitat supply models, (4) apply the models to the western portion of the TSA, (5) summarize stand and habitat conditions (suitability, capability), and (6) draw interpretations regarding habitat elements and resiliency of wildlife habitat to extensive ecological change (mountain pine beetle, timber harvest) including the identification of potential constraints on habitat connectivity, access, seral stage distributions and juxtaposition.
